Gatka (Punjabi: ਗਤਕਾ) is a traditional South Asian form of combat-training, developed by Sikhs, in which wooden sticks are used to simulate swords in sparring matches. In modern usage, it commonly refers to the northwestern Indian martial arts, which should more properly be called shastara vidiyā (ਸ਼ਸਤਰ ਵਿਦਿਆ, from Sanskrit shastra-vidya or "science of weapons"). Attacks and counterattacks vary from one community to another but the basic techniques are the same. This article will primarily use the extended definition of gatka, making it synonymous with shastara-vidiya.
Gatka can be practiced either as a sport (khel) or ritual (rasmi). The sport form is played by two opponents wielding wooden staves called gatka. These sticks may be paired with a shield. Points are scored for making contact with the stick. The other weapons are not used for full-contact sparring, but their techniques are taught through forms training. The ritual form is purely for demonstration and is performed to music during occasions such as weddings, or as part of a theatrical performance like the chhau dance. A practitioner of gatka is called a gatkabaj while a teacher is addressed as Guru or Gurudev.
